BACKGROUND

Currently, when a large number of phones or other devices are returned or exchanged, manual handling of the devices is often required. Organizations handling the returns may be required to execute a series of actions (e.g., touch events) such as unlocking the device, opening certain applications, filling in forms, configuring settings, etc. Currently, many organizations rely on human operators to follow a “script” that defines what actions to take. Such approaches are time consuming, require a one-to-one correspondence between humans and devices, and are subject to human error. Additionally, operating systems and application software often require manual input that cannot be automated for security reasons. In large volumes, the costs associated with these techniques can increase exponentially.

Other techniques to address the problem of requiring human input rely on mechanical devices that simulate human fingers. These devices, such as the SR SCARA Pro robot designed by Sastra Robotics of Kochi, India, generally include a robotic arm that manually touches a touchscreen device and, quite literally, mimics a human touching a device. These systems however suffer from the deficiencies of all mechanical systems in that the systems are vulnerable to equipment and component failures. Considering the speed and frequency of movements in such systems, such failures happen frequently.

Thus, there is a need in the current state of the art to simulate manual touch on devices such as phones, tablets, phablets etc., without requiring little or no moving parts.

BRIEF SUMMARY

To remedy the aforementioned deficiencies, the disclosure presents systems, methods, and devices for simulating human manual input for devices using capacitive touchscreens.

In some embodiments, a system may simulate a human user touching the screen of a device, such as a cell phone or similar, that has a capacitive touch screen, with the device positioned on a touch simulator that has a matrix of individually addressable, electric structures based on a matrix of individually addressable, XY resolved electric structures based on inflatable tubes an LCD display. A camera may photograph the device screen and transmit the resulting images to a computer, where the interactions of the touch simulator and the device are recorded. Additionally, software on a computer can create scripts for future, similar interactions, using the stored images to test similar devices for functionality.

In one embodiment, the system activates an icon on a device screen, using a cross-hatching of tubes. In this embodiment, rubber tubes with a slightly conductive coating are inflated. Only when two perpendicular tubes inflate does the area at the junction of the two tubes expand enough to touch the device screen. Thus when, at the junction of two inflated tubes, the upper tube touches the screen, it simulates the touch of a user. The tubes may create matrix and at the edges of matrix may be inlet valves. These valves connect to inlet chambers and, respectively, chambers are fed by a fan. By controlling the air feed into specific valves of inlet valves, one or more matrix points may be inflated so the selected points expand enough to touch the screen with the slightly conductive rubber, thus simulating a user touch. In alternative embodiments, using reduced-flow bleed valves on the opposing ends of the tubes would enable the tubes to inflate quickly, but also deflate once the inlet valve is closed. Adjusting the ratio of cross-section between inlet and bleed valves could achieve an optimum balance between speed of inflation and deflation. The problem with this approach is that it would be more difficult than the approach described infra to simulate a workable sliding motion, and achieving a workable the resolution would be difficult. Also, it would be more difficult to achieve enough transparency with those tubes so the screen can be observed to see what’s happening where and be responsive to software input. However, software on the computer controlling the matrix could be used to compensate for the sliding difficulties by trying a “soft transition” between matrix points and by erasing/compensating for much of the visual distortion created by the un-transparence of the matrix, thus reducing somewhat the disadvantages.

In one embodiment, a phone, tablet, phablet, or similar device, which is under test, sits with its display screen facing down atop a test fixture. Test fixture may be topped by a shield, made, for example, of a transparent material such as glass or polymer. Underneath is mounted a tube-based matrix (discussed supra), transparent LCD unit (discussed infra) or similar unit, which can simulate a user’s finger moving on the display of device. A camera may have a wide-angle lens that can take in the whole display area. A shield may have various different placement markings for various different devices, so an operator knows where to position each type of device so the display is in the view field of the camera. Thus the camera can view and capture what is happening on the display of device. Computer, using software, can manipulate functions on display to simulate user touches on the display of device. Most devices use capacitive touchscreens, therefore, it is important that the shield be very thin, to allow the touchscreen to sense the activities of the tube matrix or LCD. In one embodiment, an LCD is stripped of all accessory or unnecessary features, with no polarizers or other extra features; it is just two panels in series. Even the LCD itself is not necessary; only the active thin-film transistor (TFT) portion that enables changes in an electric field is used in this approach. These changes are used to simulate the touch of a human finger (or several fingers). Typically dozens of pixels are activated to represent one finger. A device is able to detect the change in the field and can be used to simulate a finger touch by moving the active area; i.e., making the display “think” it creates a visible image. However, an image (e.g., on LCD) is not actually visible. Because the polarizers have been removed, the LCD simulates a finger touch. A computer, typically, may have a display, keyboard, and a pointing device. It may be connected to a network and/or to tablet through a wireless connection. Tablet may have software that displays images from camera, in this case, the image of device as image or outline on the tablet display. Software is typically used only to set up (and record) new procedures for new software on device under test (DUT). In this example an icon on the display of device appears as an icon on the tablet within an outline of the DUT. The operator may now choose from the icons what functions he wants to perform on image; that is, for example, he can touch an icon to perform a slide, single-tap, double-tap, multi-tap, squeeze, stretch, etc. Although a tablet is discussed herein, the same functions maybe performed on a screen connected to computer, directly or indirectly, using mouse and keyboard, or using a touchscreen or other, similar apparatus or input device. The computer records and/or stores any functions and following steps, etc. as well as transmitting them to the tube matrix or LCD, which then simulates the use of a finger function on device. In this manner, an entire script of operations for a specific type and model of device with its specific software can be created on the tablet and used to test every device of that type. Further, such a test script may be run at variable speeds, that is, real-time speed, faster, slower, etc. Once a set of scripts is created, any script can be recalled from the keyboard, or even by the computer just by recognizing the device plugged in, and the whole sequence can be played back without any human interaction. In some cases, the camera can recognize (based on certain previously made selections during creation of scripts) that additional input is necessary, such as adding a password, etc. and typing that into the screen-based keyboard on device.

Also disclosed is an exemplary stripped LCD, discussed supra. The LCD has glass, tabs, driver chips, an LCD controller, connections, video card, and a PCI connector. PCI connector typically plugs into a computer such as a notebook or desktop, depending on the type video card and the bus in the computer. PCI connector may be plugged into a computer such as computer, which may then drive the LCD. Pixels on the LCD display indicate an area of activity applied over an icon on device to activate the icon. By using LCD pixels that have similar resolution to those on the device under testing, smooth motions such as, for example, slides or multi-taps may easily be simulated and applied to the device.

DETAILED DESCRIPTION

The present disclosure will now be described more fully hereinafter with reference to the accompanying drawings, which form a part hereof, and which show, by way of illustration, certain example embodiments.

In the illustrated embodiments, a system simulates a human user touching the screen of a device that has a capacitive touchscreen, with the device positioned on a touch simulator that has a matrix of individually addressable, XY resolved electric structures based on inflatable tubes. In such a system, a camera may photograph the device screen and transmit the resulting images to a computer, where the interactions of the touch simulator and the device are recorded. Additionally, software on a computer can create scripts for future, similar interactions, using the stored images to test similar devices for functionality. Alternatively, the system may simulate human touch on the device screen through a matrix of individually addressable, electric structures based on an LCD display.

FIGS. 1A through 1D are diagrams of tube-based systems for simulating human input according to some embodiments of the disclosure.

As illustrated in FIGS. 1A through 1D, systems 100 a-d include two layers of rubber tubes 102 a-e and 104 a-c. In one embodiment, rubber tubes 102 a-e and 104 a-c comprise rubber tubes having a slightly conductive coating. In the illustrated embodiment, the rubber tubes may be inflated and deflating using air supplied by a fan or other device.

In the illustrated embodiment, the two layers of rubber tubes 102 a-e and 104 a-c form a matrix of individually addressable electric structures in the form of tubing with junctions forming between the two layers, such as junction 114. As described in more detail herein, when two perpendicular tubes are inflated, the junction between the two tubes increases in height and thus protrudes from the plane formed by tubes 102 a-e and 104 a-c. In one embodiment, the plane formed by tubes 102 a-e and 104 a-c may be placed a predefined distance from a capacitive touchscreen such that the tubes 102 a-e and 104 a-c do not touch the touchscreen when uninflated (or are a suitable distance away to prevent conductivity between the tubes 102 a-e and 104 a-c and the touchscreen). Upon inflation, a junction (e.g., 114) may expand vertically and come within a predefined distance of the touchscreen, or may touch the touchscreen. In one embodiment, the tubes 102 a-e and 104 a-c may be connected to an electricity source and thus may conduct electricity. Upon a junction 114 rising and meeting a touchscreen, electricity is transferred between the junction 114 and the touchscreen, thus simulating a touch event at the junction 114.

As illustrated in more detail in FIG. 1D, inlet valves 106 a-e and 106 f-j may be connected to tubes 102 a-e and 104 a-c, respectively. In the illustrated embodiment, inlet vales 106 a-j control the flow of air into tubes 102 a-e and 104 a-c. In one embodiment, inlet vales 106 a-j may comprise reduced-flow bleed valves.

Inlet valves 106 a-j are connected to chambers 108 a-b, and chambers 108 a-b are connected to a fan 112 via channels 110 a-b and to tubes 102 a-e and 104 a-c via inlet valves 106 a-e and 106 f-j. In one embodiment, a fan source 112 may supply a constant stream of air flow buffered by chambers 108 a-b (e.g., via an exhaust valve). In one embodiment, input valves 106 a-j may be controlled via software running on a workstation (not illustrated). By controlling the air feed into specific valves of inlet valves 106 a-j, one or more junctions (e.g., junction 114) may be inflated so the selected points expand enough to touch the screen with the slightly conductive rubber, thus simulating a user touch. Conductivity is such as to simulate the touch of human skin, so that skin sensors will recognize the rubber as skin touch.

In alternative embodiments, the system 100 d may additionally include reduced-flow bleed valves (not illustrated) on the opposing ends of the tubes 102 a-e and 104 a-c. Use of reduced-flow bleed valves enables the tubes 102 a-e and 104 a-c to inflate quickly, but also deflate once the inlet valves 106 a-j are closed. Adjusting the ratio of cross-section between inlet 106 a-j and bleed valves achieves an optimum balance between speed of inflation and deflation. In alternative embodiments, valves may be configured as positive or negative flow valves.

In one embodiment, the systems 100 a-d may utilize software on a workstation to controller the matrix of tubes 102 a-e and 104 a-c and compensate for difficulties in performing certain touch events, such as “swipes” or “slides.” In this embodiment, the software may perform a soft transition between junctions in order to compensate for the delay caused by the physical nature of the systems 100 a-d. In another embodiment, the systems 100 a-d may utilize software to compensate for any distortions in video captured through tubes 102 a-e and 104 a-c. Specifically, in one embodiment, tubes 102 a-e and 104 a-c may be formed of a clear material but may still degrade the video captured of the device under test. In this embodiment, software may perform various image processing operations in order to compensate for any distortions caused by the lack of complete transparency of the tubes 102 a-e and 104 a-c. For example, software may perform operations to detect borders of objects and may utilize a catalog of device characteristics (e.g., known object shapes) in order to “rebuild” the user interface in spite of distortion.

In alternative embodiments, the systems 100 a-d may include a plurality of inflatable “pillows” forming a matrix of inflatable pillows in contrast to a matrix of intersecting tubes. In these embodiments, each inflatable pillow may be of a predefined area which may be configured based on the device or needs of the operator. In one embodiment, an inflatable pillow may be configured to be a similar area to that of a human finger. In these embodiments, each pillow may be coupled to an inlet valve and/or bleed valve in order to control the inflation of each pillow. As discussed previously, each pillow may be coated with an electrically conductive coating in order to simulate human touch events.

FIG. 2 is a flow diagram illustrating a method for simulating human input using a matrix of conducting tubes according to some embodiments of the disclosure.

In step 202, the method 200 records a simulation. In one embodiment, recording a simulation may comprise recording touch events on a touchscreen that simulates a device under test as described in connection with FIG. 7 .

In step 204, the method 200 converts the simulation to a matrix representation. As described previously, a simulation may include a plurality of touch events and the locations (e.g., X/Y coordinates) of those touch events. In order to convert the coordinates and event types to a matrix representation the method 200 first calculates a tube inflation level corresponding to the event (e.g., depending on the force of the event) and then converts the coordinates of the event to one or more tube junctions present within the matrix as illustrated in FIGS. 1A through 1D. If the event has a duration, the method 200 additionally repeats the conversion for each time series event. In this manner, the method 200 creates a time series of tube junction identifiers and inflation levels.

In step 206, the method 200 generates a valve sequence based on the matrix representation, the valve sequence controlling the air flow into a tube connected to the valves. In one embodiment, a valve sequence may comprise a time series that defines the opening and closing of specific valves controlling the matrix of tubes illustrated in FIGS. 1A-D. Alternatively, or in conjunction with the foregoing, the time series may also include a valve opening amount for each time series entry, thus controlling the amount of air flow through the valve.

In step 208, the method 200 initializes the valves associated with the matrix of tubes. In one embodiment, initializing the valves may comprise closing all valves. Alternatively, initializing the valves may comprise opening or closing valves depending on the desired initial state of the test fixture.

In step 210, the method 200 starts the fan connected to the test fixture and then, in step 212, executes the valve sequence. In one embodiment, executing a valve sequence may comprise transmitting a signal to each valve indicating the amount the valve should be opened or close at any given moment in time. By opening and closing the valves, the method 200 corresponding inflates and delates the tubes connected to each valve and thus inflates the intersection of tubes to simulate human contact. Thus, by executing the valve sequence, the method 200 transmits touch events to a devise under test based on the recorded simulation. In alternative embodiments, the method 200 may additionally include a step of executing one or more pre-loaded software applications on the mobile device (e.g., in response to a user touch event). In these embodiments, the pre-loaded software may be configured to execute a predefined set of actions where touch is not required.

FIG. 3 is a diagram of a test fixture according to some embodiments of the disclosure.

As illustrated in FIG. 3 , a device 302 is placed on top of a test fixture 300. In one embodiment, device 302 may comprise a phone, tablet, phablet, or similar device having a capacitive touchscreen interface. In the illustrated embodiment, device 302 may be placed “face down” such that the capacitive touchscreen is flush with the top side test fixture 300. In the illustrated embodiment, the top side of test fixture may be of any size suitably larger than the device 302 so as to encompass the entire touchscreen of device 302.

In some embodiments, test fixture 300 may include a shield 304 located on the top side of the test fixture 300. In one embodiment, shield 304 comprises a thin, transparent or translucent layer separating the device 302 from LCD unit 306. In one embodiment, shield 304 may be made of glass or polymer. In some embodiments, shield 304 may be permanently fixed to the sidewalls 308 a, b of test fixture 300. Although illustrated at an angle, sidewalls 308 a-b may additionally be vertical supports. Notably, shield 304 may be sufficiently thin enough so as to allow the touchscreen to sense the activities of LCD unit 306. In alternative embodiments, a matrix of tubes (as discussed in connection with FIG. 1 ) may be utilized in place of LCD unit 306. In these embodiments, the physical touching of intersections of tubes may be made with shield 304 and thus manipulate a screen of a device under test. In some embodiments, shield 304 may include one or more openings to allow for human contact. For example, a mobile device may include one or more elements (e.g., a “home” button) that requires human skin to function (e.g., by requiring a thumbprint or similar skin-based requirement). In these embodiments, shield 304 may be device-specific and may include an opening on those portions of the device that require contact with human skin.

Test fixture 300 additionally includes a matrix of individually addressable electric structures in the form of a transparent LCD unit 306. As discussed in more detail, LCD unit 306 may be sufficiently transparent to allow for light from device 302 to pass through shield 304 and into the body of test fixture 300 with minimal or no distortion. In the illustrated embodiment, LCD unit 306 is configured to simulate a user’s finger moving on the display of device 302. In one embodiment, LCD unit 306 may be fixedly mounted to shield 304. Alternatively, or in conjunction with the foregoing, LCD unit 306 may be fixedly mounted to one of sidewalls 308 a-b and placed flush with shield 304. Operation of the LCD unit 306 is described in more detail with respect to FIGS. 4 and 5 , the disclosure of which is incorporated herein by reference in its entirety. In one embodiment, LCD unit 306 may include two layers of active thin-film transistors arranged in a matrix.

Test fixture 300 additionally includes a camera 314 having a wide-angle lens 312. In the illustrated embodiment, the camera 314 and lens 312 may be configured to capture the entirety of the touchscreen of device 302. As illustrated in FIG. 3 , lens 312 may be selected such the field of view (represented by lines 310 a-b) is broad enough to capture the entirety of the touchscreen of device 302 or larger.

In some embodiments, shield 304 may include one or more markings associated with various sizes of a device 302. For example, shield 304 may include four “L”-shaped markers representing the four corners of various devices. In this manner, shield 304 allows for the proper positioning of device 302 such that the touchscreen of the device is located entirely within the field of view of camera 314.

Test fixture 300 additionally includes an input/output (“I/O”) port 318. I/O port 318 allows for the transmission of data to and from camera 314 and LCD unit 316, as described in more detail with respect to FIGS. 4 and 5 . In the illustrated embodiment, LCD unit 306 may be connected to I/O port 318 via connection 316, thus allowing for communication with a workstation or other device as described more fully in connection with FIG. 5 .

FIG. 4 is a block diagram of a system for simulating human input according to some embodiments of the disclosure. As illustrated in FIG. 4 , a system 400 includes a glass panel 402, tabs 404 a-b, driver chips 406 a-b, LCD controller 410, video card 412, and PCI connector 414.

In one embodiment, glass panel 402 may comprise a planer sheet of active thin-film transistor (TFT) glass. Generally, a standard TFT LCD display consists of multiple layers. In a standard LCD display a sheet of TFT glass is surrounded by one or more color filter glasses and one or more polarizers. In the illustrated embodiment, glass panel 402 may comprise only the TFT glass layer of a traditional LCD display. By using only the TFT glass layer, the system allows for full transparency while allow for the conduction of electricity using the TFTs present within the glass panel.

In one embodiment, glass panel 402 may comprise two TFT panels in series. In one embodiment, glass panel 402 may additionally be coupled to a liquid crystal display; however, in alternative embodiments a liquid crystal display is not necessary. A liquid crystal display may not be necessary as only the active TFT layer that enables changes in an electric field is used in the illustrated embodiment. These changes are used to simulate the touch of a human finger (or several fingers).

Illustrated on glass panel 402 are multiple, active pixels 408. Although illustrated as darkened circles, in practice, active pixels 408 would be invisible in operation due to the lack of color filters installed over the TFT glass. Active pixels 408 indicate an area activity applied, for example, over an icon on a device under test that, in turn, activates the icon. By using LCD pixels that have similar resolution to those on the device under test, smooth motions such as slides or multi-taps may easily be simulated and applied to the device.

Generally, dozens of pixels are activated to represent a single finger. A test fixture is able to detect the change in the electrical field of glass panel 402 and the change be used to simulate a finger touch by moving the active area; i.e., making the display “think” it creates a visible image. However, an image (on glass panel 402) is not actually visible as the polarizers of the LCD have been removed. Thus, the glass panel 402 of the LCD may simulate finger touches without displaying visual content.

Glass panel 402 may be connected to one or more tabs 404 a-b. Tabs 404 a-b may allow for the positioning and retention of glass panel 402 within a test fixture. Additionally coupled to glass panel 402 are driver chips 406 a-b. In one embodiment, a driver chip may comprise a solid-state active or passive electronic device that allows for the manipulation of transistors within glass panel 402. In the illustrated embodiment, the system 400 includes two driver chips 406 a-b in order to control a horizontal and vertical set of transistors present within glass panel 402.

Driver chips 406 a-b are communicatively connected to an LCD controller 410. In one embodiment, LCD controller 410 comprises a solid state device designed to convert instructions to signals for driver chips 406 a-b. In alternative embodiments, LCD controller 410 and driver chips 406 a-b may be collocated or may comprise a single chip. In one embodiment, LCD controller 410 may be configured with an image processor designed to convert bitmap images into instructions for driver chips 406 a-b. As illustrated in FIG. 4 , the system 400 may further include a video card 412 designed to receive video data from a computer via PCI connector 414 and transmit video content to LCD controller 410.

The system 400 additionally includes a PCI connection 214. PCI connector 414 typically plugs into a computer such as a notebook or desktop, depending on the type of video card 412 and bus in the computer. PCI connector 414 may be plugged into a computer which may then drive the glass panel 402 via LCD controller 410.

FIG. 5 is a block diagram of a system for simulating human input using a simulated device according to some embodiments of the disclosure.

As illustrated in FIG. 5 , test fixtures 502 a-n are communicatively coupled to workstation 504. In one embodiment, each test fixture 502 a-n may comprise a test fixture as described in connection with FIGS. 3 and 4 , the disclosure of which is incorporated herein by reference in its entirety. In some embodiments, text fixtures 502 a-n may include a tube-based or LCD-based test fixture.

Workstation 504 may comprise a memory 506 storing applications 506 a-n. Memory 506 may comprise any type of volatile memory device such as RAM, SRAM, DRAM, etc. In one embodiment, applications 506 a-n may provide for the manipulation of an LCD display present within test fixtures 502 a-n. For example, applications 506 a-n may allow for the storage and retrieval of operations stored in long-term storage (not illustrated). Additionally, applications 506 a-n may allow for the editing of operations as well as the transmission of operations to test fixtures 502 a-n. In one embodiment, workstation 504 may record operations received from tablet 518 as discussed more fully herein.

Workstation 504 additionally includes a display 510 (e.g., a CRT or LCD monitor or similar display), a keyboard 512, mouse 514, and network interface (NIC) card 516. In one embodiment, NIC card 516 may comprise an electronic device enabling network connections with other devices such as test fixtures 502 a-n or tablet 518. In one embodiment, NIC card 516 may provide wireless or wired network connectivity.

Tablet 518 may comprise a tablet computer, phablet computer, mobile phone or other portable device having a touchscreen display. As illustrated, tablet 518 includes a display 522 which comprises a touchscreen display and memory 520 which is configured to store one or more applications 520 a-n. Operation of tablet 518 and functions performed by applications 520 a-n are described more fully in connection with FIG. 6 , the disclosure of which is incorporated herein in its entirety.

As illustrated above, an entire script of operations for a specific type and model of device with its specific software can be created on tablet 518 and used to test every device of that type. Further, such a test script may be run at variable speeds, that is, real-time speed, faster, slower, etc. Once a set of scripts is created, any script can be recalled from the keyboard 512, or even by the workstation 504, just by recognizing the device under test after connected. In one embodiment, the whole script of operations can be played back without any human interaction. In some cases, the camera within a test fixture 502 a-n can recognize (based on certain previously made selections during creation of scripts) that additional input is necessary, such as adding a password, etc., and an operator may type the required information into the screen-based keyboard on the device under test or view keyboard 512.

FIG. 6 is a diagram illustrating a user interface for simulating human input according to some embodiments of the disclosure.

As illustrated in FIG. 6 , a tablet device 600 includes a display area 602 capable of displaying one or more currently running applications. In the illustrated embodiment, display area 602 illustrates an application that includes a depiction 604 of a device and a plurality of operation icons 608 a-d.

In the illustrated embodiment, depiction 604 may be generated based on data received from a camera placed within a test fixture such as the fixture illustrated in FIG. 3 . For example, an application running in display area 602 may include a portion of the display that presents video received from a camera. In one embodiment, the video includes video frames capturing the touchscreen of a device under test. In this manner, device 600 reproduces the visual display of a touchscreen of a device under test as depiction 604.

Notably, depiction 604 includes an exact, or approximation, of the user interface displayed on a device under test including a title bar having the time and battery percentage, as well as multiple icons 606 a-b. In the illustrated embodiment, the icons 606 a-b may correspond to the application launcher icons present on the “home” screen of a mobile device.

Device 600 additionally includes software icons 608 a-d. In the illustrated embodiment, icons 608 a-d may correspond to various applications capable of being executed on the device 600, and separate from the applications on a device under test. Icons 608 a-d may provide access for numerous features discussed in further detail herein. For example, icons 608 a-d may allow for the initialization of the camera and device under test, the recording of procedures, the playback of procedures, editing of procedures, and other functionality.

One non-limiting example of the operation of device 600 is provided herein. In this example, a user of device 600 may choose from icons 608 a-d what functions he or she intends to perform on depiction 604. In one embodiment, the user may select icon 608 a to initialize the camera and begin the display of a device under test as depiction 604. After initialization, the user may select icon 608B to being a recording function allowing for the recordation of one or more operations to be performed within depiction 604. For example, operations to perform on depiction 604 may include one of a single-tap, double-tap, multi-tap, squeeze, stretch, or other gesture.

After completing the operation (or sequence of operations), the user may select icon 608 c to save the recorded operations to memory or disk. Alternatively, the user may select icon 608 c to playback the operations. Prior to playing back the operations, the user may select another icon to reset the device under test to a known state. Finally, the user may also utilize icon 608 d to enter an editing state wherein the user can manipulate one or more operations recorded previously. For example, the user may speed up or slow down various operations based on determining that an operation was performed too quickly or too slowly.

Although a tablet device 600 is shown here, the same functions maybe performed on a screen connected to computer, directly or indirectly, using mouse and keyboard, or using a touchscreen or other, similar apparatus or input device.

FIG. 7 is a flow diagram illustrating a method for simulating human input according to some embodiments of the disclosure.

In step 702, a device under test is placed on a test fixture. As discussed previously, a device under test may be placed on a test fixture with the device’s touchscreen facing the test fixture.

In step 704, a camera in the test fixture is enabled. In one embodiment, a camera may automatically be enabled upon detecting that a device under test has been placed on the test fixture. Alternatively, a camera may be enabled upon detecting a connection between the device under test and a workstation.

In step 706, an image of the device under test is displayed on a tablet device. In one embodiment, the camera may record the screen of the device under test and transfer image data of the device under test to a tablet device. In one embodiment, the image data may be transmitted to a tablet device via a workstation.

In step 708, the method 700 records a simulation event. In one embodiment, a simulation may comprise the manipulation of the device under test via the video images displayed on the tablet. That is, the tablet may be configured to receive touch input from a user and translate the touch input on the tablet device to touch input on the device under test using the video image of the screen of the device under test.

In step 710, the method 700 transmits simulation data to the LCD display. In one embodiment, the method 700 may transmit simulation events as recorded to the LCD display which, in turn, performs the simulation events on the device under test. In response, the camera captures the screen of the device under test and transmits the resulting image to the tablet, thus allowing the tablet to reproduce the results of the simulation event. For instance, a user may “tap” an icon on the tablet corresponding to an icon on the device under test. In response, the method 700 stores the “tap” event (including coordinates, tap duration, etc.) and transmits the event to the device under test via a workstation (as discussed in more detail below). In this manner, the method 700 generates a listing of touch events or operations and records these events as a simulation. In one embodiment, a simulation may comprise a form-filing operation. Alternatively, the simulation may comprise operations designed to test the functionality of the device.

The method 700 continues until the simulation is deemed complete in step 712. In this manner, the method 700 continuously transmits simulation events and displays the screen of the device under test on the tablet, mimicking the display of the device under test and allowing a user to view the results of the simulation in real-time.

In step 714, the method 700 saves the simulation. In one embodiment, saving a simulation may comprise generating a final simulation description (e.g., a sequence of touch operations) and transmitting the simulation to a permanent storage location such as a workstation or other networked device.

In step 716, the method 700 runs the simulation. In the illustrated embodiment, running a simulation may comprise transmitting the simulation events to a device under test (or multiple devices under test) at a time subsequent to the recording of the simulation. In this manner, the method 700 allows for a single recording of a simulation and allows for playback of the simulation as desired in the future and for other, similar devices.
